地下水水氡現地揮發機制被提出用來解釋自2003年7月起至今在安通溫泉已捕捉到三次地下水水氡濃度異常下降的地震前兆，(1)2003 = 6.8 成功地震,(2)2006 = 6.1 台東地震,及(3)2008 = 5.4 安通地震。以上三次地震震央分別距離安通溫泉水氡監測井(D1)24 公里、52公里和13公里。為支持地下水溶解氣體現地揮發機制，在2010/11/30至2011/3/15期間同時監測安通溫泉地下水水氡、甲烷及乙烷。從水氡、甲烷及乙烷同步的濃度變化趨勢間接證實地下水溶解氣體現地揮發機制。另外，建議在安通溫泉同時觀察地下水三氯氟甲烷及其他溶解氣體(水氡、甲烷及乙烷)的濃度變化，有機會進一步佐證地下水溶解氣體現地揮發機制。

Radon volatilization mechanism into the gas phase was hypothesized to explain the anomalous declines in groundwater radon precursory to three major earthquakes – (1) 2003 MW = 6.8 Chengkung, (2) 2006 MW = 6.1 Taitung, and (3) 2008 MW = 5.4 Antung in Taiwan. The epicenters were located 24 km, 52 km, and 13 km, respectively, from the Antung radon-monitoring well D1. To verify the mechanism of in-situ volatilization, we monitored groundwater-dissolved ethane in addition to radon and methane at well D1 in the Antung hot spring from November 30, 2010 to March 15, 2011. The mechanism of in-situ radon volatilization has been corroborated by the simultaneous concentration changes in groundwater-dissolved radon, methane, and ethane observed during the above time period. It is recommended to monitor trichlorofluoromethane (CFC-11) in addition to radon, methane, and ethane at well D1 to further support the mechanism of in-situ volatilization.
